Kollins is a modern American spelling of Collins, an Irish and English surname that goes back to the Gaelic Ó Coileáin, "young hound", or to a medieval pet form of Nicholas. The k spelling turns a surname name into something unmistakably new, in the style of Kinsley and Kamryn. Kollins was almost unused in 2000 and has climbed steadily to number 1376 in 2024 and number 1568 among US girls' names in 2025.
